An Idea; Decrease your "Hot Air Tuning Curve"

[Jerryl]

The problem(s)
Most of the HA folks understand how finicky these cars are in the tuning area.
Let's say the car is “tuned”, you turn the alky knob (up or down), and you now need to re-tune? Or,
You fill up with race gas and now need a lower AFR target, and you burn your race gas just to get the tune close to the desired AFR?

So you start the re-tuning process.
You watch your WB or NB and pull/add fuel to the chip, or change the FP at the regulator. A very cumbersome and time consuming process, and frustrating at times! (Agreed so far?)

What is out there to help me cut my tuning time and associated cost down?
A Wide Band Controlled chip!
Wide Band controlled chips and aftermarket systems have been around for a while. But wait, the target market has been the IC'd cars and most want nothing to do with the HA cars!
From my observations, the prices vary from around the $450 - $1800 mark.
What we (HA Community) need is a set-up that would do the same for around the $150 mark!

The project goal; Wouldn't it be nice to have a chip where you set the target AFR, and allow the ECM to do what it does best?; Control your AFR
So, you would set your target AFR and let the ECM adjust the fueling for;
1. Changes in Alky knob setting
2. Changes in ambient air changes (Temp, Baro, etc)

Someone working on this for the HA Cars?
YES!
Can you say “Turbo Tweak”?

When will this be available?
Glad you asked.
The “Eagle has Landed” from Turbo Tweak®!
You get the ability to adjust;
1. Lock-up - Converter MPH Lock
2. AFR - Part throttle
3. AFR – 1st-2nd WOT throttle
4. AFR – 3rd – 4th WOT throttle
5. Base WOT fuel
6. Spark Timing - WOT 1-2 gears
7. Spark Timing - WOT 3-4 gears
8. WOT fueling boost level

What do I need to make it work;
1. Power logger if you do not have one (Avilable from TurboTweak)
2. A custom chip for your set-up that fits in the stock ECM

How do I tune this set-up?
EASY! You set your target AFR.
That’s it! The ECM will do what it does best; Control your AFR!

How does it all work?
Actually, it works EXCELLENT!
You may need to make some minor adjustments to get into the AFR window "your car likes".

What else?
A chip that plugs into a stock 87 ECM that adjusts your Part & WOT fueling to meet your AFR target for $150 specifically for a HA?

As always, make sure you do not have mechanical problems and/or basic 101tuning problems.


COOL stuff, no matter whcih way you turn it!

Hi Jerryl, Nice to see you really didn't retire

This chip sounds really exciting and payday is less than a week away, so I'm probably going for it really soon.

TT Rules!!!

 

[esinger]

Wait a second, I went to the TT site and it's only for 50 lb injectors of larger.

So it will not work with 009s?

 

[BRAD_PADGETT]

Eric- I have the exact setup that Jerryl is talking about. I was one of the test setups last fall. My setup is designed by Jerryl and TT. Global warming resulted in a bad winter and tax season slowed me down.

I chose this route fom Jerryl trying to stop knock problems. I even sent my TA33C out for a rebuild last December. Solved the knock issue in March. This chip along with the wideband O2 sensor on rhe test pipe with a powerlogger rocks. I am running 18 lbs boost, Razor, on 93 octane no knock on a stock turbo. This setup will break the MT drag radials loose before hookup. I will put the TA33C on in three weeks. Brad- I have not retired either-tired of stupid questions about cutting up a Hot Air as well as Hot Air people who keep secrest. I do not keep secrets. Brad

Good to see you guys again.

I didn't know this setup existed. IMO, this is the only "right" way of doing it. Thanks very much, Jerry. I'm just about to order my 60lbers and chip for the second time.

Brad, if you don't mind me asking, how much did this run you? So you just set a target A/F and the car hits it, no matter if you change boost/mods? Can you set it to run a little rich in case you're running a lot of methanol?

If it does what it says it does, I can't imagine going with any other setup with the stock computer.

I tried to open the instructions but it won't open on my computer.

This is very bad advise.... But, I've run a 60lb chip with 009s and vice versa. You could potentially run their 50lb chip with your 009s and run a little more fuel pressure. You may get a tip in stumble and you may not. I'm not recommending it, and it's bad advice but it worked fine for me.

 

[Turbo6Smackdown]

Wow, that's really good to see for the HA guys. I'm glad to see they got some new toys. Makes me even more confident to buy a hot air. Was toying around with the idea of one for years because theyre so much more inexpensive. This is good good news.

 

[esinger]

Boy, I'm having enough problems with the car running rich with the 009's. 50 lb injectors would be nice, but currently I don't need that much fuel, let alone going 009s with a 50 lb chip.

I guess the big questions is why can't the chip be burned for 009 injectiors?

Brad, I hear you buddy, I'm not happy about people making their HA cars IC either, but it's their cars and they can do whatever they want to them.

 

[Jerryl]

............... I guess the big questions is why can't the chip be burned for 009 injectiors? ............

Eric,
This will not be a problem.
Brad has the 009's and has been running this set-up for a while.
Contact TT on this.

For those who are "thinking" about this chip;
You have no idea how nice this chip is!
Sometimes it is "What you DON'T do" that counts.

I am just blessed to have someone like TurboTweak willing to put the research time into a HA, and help me get this thing to run right!

Matt- The setup does exactly what Jerryl and Eric at TT designed. The chip has been around at least since last summer. TT does not advertise it and Jerryl had me test it on my car. The chip cost around 125( I don't remember exactly), powerlogger $250 and a wideband O2 sensor $250. You put the wideband O2 sensor on the test pipe and run the wiring into the car through the shifter cable port under the center console to the powerlogger. The chip automatically adjusts A/F ratio based on the wideband O2 sensor and the 3 bar MAP. Injector size is not a factor- I run 42s. The TT chip is programmable just like Jerryl stated. There is no BS here at all. Call me if you like. Brad

 

[esinger]

Okay, you guys have convinced me, I've gone ahead and used the old credit card ordered one. I imagine that the TT chip must change the injector pulse width to tweak the fuel flow in order to get the target AFR, so I see your point Jerryl that it doesn't really matter that much about the injector size.

Too bad I didn't know about this sooner. I just ordered a new chip from Eric at TT about 2 months ago

Eric at turbo tweak is great to do business with, top notch all the way.

That's awesome! Now I know what my stimulus check is going to. This is almost as good as the aftermarket ECMs and probably has better drivability and fuel economy. I'm very glad I didn't order my chip yet.

What exactly is the powerlogger? I assume it's some kind of data logger?

The only other thing that bothers me is how sensitive it the wideband to leaded race gas when it's downstream in the exhaust? I'm going to be running alky this time around but I get 100LL so cheap I may do a mix from time to time.


Also, I've seen widebands as cheap as $80 since they're OEM equipment on a lot of new cars. Do we have to use the one that comes with the kit?

Matt- The powerlogger is the latest logging tool out there and it attaches to an 87 ECM and a laptop. I got mine from Fullthrottle Speed along with a Zeitronix wideband O2 sensor. The powerlogger and O2 sensor are separate items. The wideband O2 sensor connects to the powerlogger and you keep your existing O2 sensor. I run 93 octane unleaded. I can get 100 octane unleaded here but it is expensive. I would recommend dropping the leaded fuel and go with 100 octane unleaded. Remember- the wideband O2 sensor has to be down by the test pipe in order to reduce the heat exposure from the turbo and downpipe. Take care. Brad

 

[Rottydogg84GN]

What Brad is stating is straight to the point and he does not BS you as long as you are straight with him. Brad I got the scanmaster and will be hooking it up real soon and installing the GM seals like you said

 

[esinger]

Got it

When I came home yesterday there was a small box in the mail from TT!

Setup the LC-1 wideband as the directions described, updated the powerlogger software (not required, but I realized yesterday there was a new version) and put the chip in and left the settings at their default values. I didn't do any 1/2 or full WOT runs, just basic driving around. The car feels strong just cruising around and letting the ECM learn.

I'd love to take it to the track this weekend, but temperatures are going to be in the high 90's and I don't want to punish both me and the car. I'll post more as I get more miles on it.

Thanks Eric M. for a great chip that fits the bill!

Hey guys,

I think this is an awesome thing. Thanks goes out to turbo tweak.

I would like to run E-85. Would this set-up be able to keep up with the demands. Of course with the supporting mods to go along with it.

I also would like to run alky on top of that down the road.

Would this work?

Thanks
